The structure of amino acid glycine is as follows:



Thus the molecular formula for Glycine is${\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}_2{\mathrm{N}}_1$When 10 glycine molecules come together to form a polypeptide chain, 9 peptide bonds will be formed by the loss of 9 water molecules. Thus the molecular formula of the polypeptide will be$\left[\left({\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}_2{\mathrm{N}}_1\right)\times 10\right]-9{\mathrm{H}}_2\mathrm{O}={\mathrm{C}}_{20}{\mathrm{H}}_{32}{\mathrm{O}}_{11}{\mathrm{N}}_{10}$
